Here you can see two screenshots of the current map editor. It is planned that the user can pick a tile from the tileset and place it on the map.
In the past few weeks I improved the map display algorithm so that it is much more faster now. The maps are now loading so fast that there is actually no noticeable delay.
The maps still look messy since the tilesets aren't correct. But that is something I'm working on.
I might upload a new version in the next few weeks. There I will insert some error outputs so that I might be able to find the reason the editor isn't running correctly for some of you..
